Product Information

The series of swing clamp cylinder is ideal for workpiece clamping which requires a sufficient space for convenient workpiece loading and unloading and high pressure clamping.
It provides swing motion (do not clamp workpiece) and vertical holds down motion.
The swing clamp cylinder employs Germany oil seal and imported parts. The inside surface of cylinder barrel is specially treated, featuring maximum smoothness, high performance and long service life.
For maximum oil feeding speed, refer to specifications. Do not exceed oil feeding speed to avoid too high swing speed. ln case improper swing speed occurs, it is suggested to equip with an additional oil flow control valve to reduce oil feeding speed.

Max. operating pressure: 250 kgf/cm²
Min. operating pressure: 70 kgf/cm²
Single acting and Double acting
The acting speed of clamping-unclamping should be slowed down.
For customized clamp arm, please don't exceed 1.5 times of the original length and weight.
The methods to mount & remove and the rotation diagram of the clamp arm, please refer to Q&A.

Usable fluid:
General Hydraulic Oil Equivalent to ISO-VG-32.
